My lights I dont think have ever worked. I know the coast button has always be flakey. But the cruise has always set fine. where do I get this coil and how hard is it to change?

I had the same problem as Speedy but there were no blown fuses...Just enough liquid in it to trip the connection some how. Either way, got it replaced and I haven't had a problem since. Might wanna make sure that's it before you start replacing the more expensive parts....I learned the hard way.

I have had 2 problems with my cc.The first was the brake switch.It was shorted just enough to kill my cc and flicker the brake lights once in a while.The 2nd which was similar to yours ended up being a broken tab holding the neutral safety switch in to the right of the clutch pedal.It had come loose and because I had bypassed the starting part long ago it took awhile to find the problem.

TERRCO- so all you did was fix the tab and it worked, or did you have to replace something? Just curious because I've also by passed the nuetral start switch.

Hey JD 9610 my backup lights quit working once that pressure sensor shorted out I guess its on same fuse as the backup lights. Dont recall it being listed on the cover as on that fuse but it was.

I check all fuses and they are good. I used a meter on everyone so I know they are good. how does that pressure switch work? normal open or closed trying to check it with a meter.

I'm not sure mine was just leaking fluid bad raound the top and the plug and when I replaed the blown fuse i seen small smoke and sizzle on the plug area right before it blowed the fuse. Is you pressure switch leaking fluid if not then you may have a different problem. Good Luck.

pressure switch is dry. changed the transmission range sel. On the side of the tranny and It didnt fix a thing. So now I'm way in the dark on this. No back up lights or cruise. I dont know if they are linked or not.
